Answer:

<h2>The ball has kinetic energy.</h2><h2>Kinetic energy is 945 J</h2>

Explanation:

Kinetic energy = 0.5 x Mass x Velocity²

Here the ball has mass and velocity.

So the ball has kinetic energy.

Kinetic energy = 0.5 x Mass x Velocity²

Mass = 2.1 kg

Velocity = 30 m/s

Kinetic energy = 0.5 x 2.1 x 30²

Kinetic energy is 945 J
